The load encroachment characteristic can be switched off by setting the parameter
OperationLdCh = Disabled , but notice that the DFw and DRv will still be calculated from RLdOutFw
RLdOutRv . The characteristic will in this case be only quadrilateral.
and
There are three different ways to form the internal INHIBIT signal:
• Logical 1 on functional input BLOCK inhibits the output PICKUP signal instantaneously.
• The INHIBIT internal signal is activated, if the power swing has been detected and the
measured impedance remains within its operate characteristic for the time, which is longer
than the time delay set on
logical 1 signal to the BLK_SS functional input.
• The INHIBIT internal signal is activated after the time delay, set on
appears during the power swing (input IOCHECK is high) and the power swing has been
detected before the ground-fault (activation of the signal I0CHECK). It is possible to disable
this condition by connecting the logical 1 signal to the BLK_I0 functional input.
